To all whom, it may concern:

Be it known that 1, SAMUEL H. TINsMAN, a citizen of the United States of America, and a resident of Morris, Grundy county, Illinois, have invented a certain new and useful Improvement in Cultivators, of which the following is a specification.

My invention relates to cultivators in general, but more particularly to wheeled culti' vators, and especially to wheeled or riding cultivators of that type in which the shovels are mounted on a pair of forwardly-converging bars.

Prior to my invention it has been the universal practice, so far .I am now' aware, to mount the bars or beams carrying the shovels in such manner that they were free to swing laterally about their forward points of connection with the body-frame. ith this arrangement it was necessary in cultivating corn, for example, to swing the rear ends of the shovel-beams laterally to an undesirable extent in order to permit the shovel or shovels at the forward ends of the beam to dodge or go around the corn-hills. In other words, the old arrangement necessitated a useless and undesirable extent of lateral play on the part of the rear shovels in order to enable the forward shovels to pass around the corn-hills.

Generally stated, therefore, one object of my invention is the provision of an improved construction and arrangement of parts whereby the forward shovels of the cultivator may be given a lateral play or movement sufficient to carry them around the corn-hills and without causing but a very slight lateral movement on the part of the rear shovels.

A special object is to provide an improved construction and arrangement whereby the shovel-beams may be fulcrumed at their rear ends and connected with forward and laterally swinging draft-bars so as to permit the forward shovels to be shifted readily to one side, as in dodging or passing around a cornhill, Without causing but a very slight lateral movement on the part of the rear shovels.

Prior to my invention it was also the practice in oultivators having laterally swinging or adjustable gangs that is to say, gangs which are laterally shiftable or adjustable at ing the principles of my invention.

will for the purpose of dodging a corn-hill or other obstruction-to raise and lower the shovel-beams by swinging them vertically about their forward ends, it being necessary with this arrangement to lift the rear ends of the beams considerably and to an undesirable extent in order to raise the forward shovels to the proper distance above the ground, and even then the forward shovels were not always raised sufficiently.

Generally stated, it is also an object of my invention, therefore, to provide an improved arrangement for lifting and lowering the shovel-beams bodily, the shovels all having the same degree of vertical adjustment.

Another special object is to advantageously combine the said feature of bodily-vertical adjustment of the shovel-beams with the said feature of swinging the shovel-beams laterally about their rear ends.

It is also an object to provide certain details and features of improvement tending to increase the general efficiency and se rviceabil- 'ity of a cultivator of this particular character.

The nature and ad vantages of my invention will, however, hereinafter more fully appear.

In the accompanying drawings, Figure 1 is a plan of a wheeled or riding cultivator embody- Fig. 2 is an enlarged detail of one of the draft connections. Fig. 3 is a view similar to Fig. 1, but showing the forward end of one shovel-beam swung laterally to one side. Fig. 4: is an enlarged detail showing one of the draft-bar connections with the beam. Fig. 5 is a side elevation of the cultivator shown in Fig. 1. Fig. 6 is a View similar to Fig. 5, but showing the beams or shovel-gangs raised from the ground.

Fig. 7 is a detail view of one of the connec' tions between the frame-bars and the axle. Fig. 8 is an enlarged detail view of the casting for connecting the draft-rods with the tongue, showing adjacent parts. Fig. 9 is a detail view of one of the fulcrum bars and ad jacent parts.

As thus illustrated, my improved cultivator, which, as illustrated, may be employed either as a riding or awalking cultivator in the usual and well-understood manner, comprises, preferably, a tongue or pole A, rigidly connected at its rear end portion with the arch or bail shaped axle B through the medium of the frame-bars a and a and also at a point somewhat forward of the point of connection with the said axle with the draft-rods C. With this arrangement the said axle has its side portions 5 suitably connected with the tongue by means of the bars (rand also by the castings b on the axle, rods 6 castings 0, and the said rods C. The rods 6 are connected with the castings c by means of arms 0, the latter rigid with the castings c. The rods C, it will be observed, have their forward ends pivotally secured to the casting A on the tongue. Thus the pole and the axle, together with the framebars, constitute a very strong and simple bodyframe.

The supporting-wheels D are mounted in the usual manner on the spindles or outturned lower end portions of the said axle. The usual riders seat E is secured, preferably, to the rear portion of the frame-bars (0 which latter rest on the axle and connect rigidly with the bars a.

As illustrated, the cultivator comprises two independently operated or controlled gangs, each consisting of a beam F, provided with a plurality of shovels f of any suitable known or approved character. The beam of each gang is connected, preferably, at an intermediate point, as by castings f, with a laterally swinging draft-bar f Said draft-bars can be connected with the body-frame in any suitable manner-as, for example, by mounting their upturned forward ends for rotary or oscillatory movement in the castings 0, which latter are of the form shown in Fig. 2. The rear upturned. end portions are mounted to turn or oscillate in the castings f, the latter being rigidly secured to the beams F. Preferably and in order that the two gangs of shovels may be raised or lowered these castings 0 are mounted to turn or oscillate readily upon the outturned end portions of the bars C. Thus each gang is adapted to swing laterally relatively to its allotted draft connection, and each draft-bar C is adapted to swing vertically relatively to its point of connection with the body-frame. In order, however, that the said gangs may be swung laterally in such manner as to permit the forward shovels to dodge or pass around the corn-hills without the necessity of but very little movement on the part of the rear shovels, the beam of each gang is preferably fulcrumed at its rear end-as, for example, by giving it a loose connection with one of the rearwardly-extending fulcrum-bars Gr. These fulcrum-bars are, it will be seen, suitably connected with the axleas, for example, by hinging their forward ends by means of the castings g on the lower outturned or spindle portions of the said axle, for it will be seen that it .is desirable to have the said fulcrum-bars so mounted at their forward ends that they may be readily swung up and down,

but not sidewise. If desired, the rear ends of the said fulcrumbars can simply pass through rings or openings formed in the rear ends of the beams F, whereby a sufliciently loose connection is insured to permit the gangs to be readily raised and lowered. With this arrangement and from his position on the drivers seat E the operator can place his feet upon the portions f secured to the forward end portions of the beams F. When it is desired to swing the forward shovels laterally, as is the case when it is desired to have the forward shovels pass around corn-hills, it is only necessary for the operator to shift the forward portions of the beams to one side. In this way the necessary or desired lateral shift on the part of the forward shovels is provided for without making it necessary to cause but a slight lateral shift on the part of the rear shovels. In other words, as is well known, it is the forward shovels which must be caused to dodge or pass around the corn-hills,and with my improved arrangement it is not necessary, as has heretofore been the practice, that this necessary lateral shift on the part of the forward shovels be accompanied by amuch greater and of course undesirable lateral shift on the part of the rear shovels. Practically I confine or limit the lateral shift to the shovels which require such movement.

Any suitable arrangement can be employed for raising and lowering the gangs. For example, a pair of swinging hand-levers H can be suitably supported on the upper horizontal portion of the axle and provided with the usual locking devices adapted to engage the curved racks or segments 72. These segments, as illustrated, are part of the castings Z for securing the bars a to the axle. The said hand-levers can have lower end portions it connected through the medium of chains or other flexible connections A with the beams F. Thus with this arrangement the said levers can be employed as the means for manually raising and lowering the gangs and for supporting the gangs in elevated positions. It will be seen, however, that the gangs have abodily up-anddown movement. This is owing to the fact that the rods 5 prevent the castings 0 from tilting when moved up and down and that consequently the castings b and the bars f and the beams F are held against tilting movement when the gangs are raised and lowered. During such vertical adjustment it is evident that the rear ends of the beams F Will slide backward and forward on the fulcrum bars Ur. Thus all of the shovels ave the same extent of adjustm nt, and it is n t n c ssary to raise the rear shovels higher than the others.

It will be readily understood that the cultivator thus constructed can be employed as a walking-cultivator, if such is desired, by simply attaching the usual and well-known handles (not shown)t0 the beams F. In such case the lateral movement or adjustment of the gangs ITO would be controlled by hand; but whether the cultivator is operated as a riding or walkingcultivator it is obvious that the gangs are with my improved arrangement of a character to be manually adjusted or moved laterally in such manner as to give the forward shovels the maximum or necessary lateral movement, while the rear shovels have but very little or practically a minimum of lateral movement. In this way it is obvious that I provide a cultivator which can be employed and handled in a very satisfactory manner. Furthermore, as explained, I provide a system of rods and bars which permit the gangs to have a bodily up-and-down movement as distinguished from the old and unsatisfactory upward-swinging movement, and in my improved cultivator the feature of bodilyvertical adjustment and the feature of swinging the gangs laterally about their rear ends are very satisfactorily and harmoniously combined.
